- the lower mounting bracket 70 a and the upper mounting bracket 70 b are mutually butted, to form an accommodating portion (not shown) for accommodating the quick female connector 50 and the slidable sleeve 51 .
- the diameters of the semicircular holes 72 a and 72 b are less than a size of a cross section of either of the quick female connector 50 and the slidable sleeve 51 , which therefore can prevent the quick female connector 50 and the slidable sleeve 51 that are accommodated in the accommodating portion from being detached from the accommodating portion from the semicircular holes 72 a and 72 b.
- the quick male connector 60 When the quick female connector 50 and the quick male connector 60 are connected, the quick male connector 60 is inserted into the quick female connector 50 , and when a side wall corresponding to the semicircular hole 72 a withstands the quick female connector 50 , the quick male connector 60 can be smoothly inserted.
- a drawing force is exerted on the quick male connector 60 , and the quick male connector 60 and the quick female connector 50 that are connected move towards one side of the semicircular hole 72 b by a distance.
- a leftward reactive force in a location direction in FIG. 3
- the lower mounting bracket 70 a and the upper mounting bracket 70 b is exerted on the slidable sleeve 51 , and therefore, the quick male connector 60 can be pulled out.
- the cross section of the quick female connector 50 is hexagonal, the whole slidable sleeve 51 is of a cylinder structure, and the size of the cross section of the quick female connector 50 is greater than a transversal size of the slidable sleeve 51 .
- internal space of either of the lower mounting bracket 70 a and the upper mounting bracket 70 b is provided with two-section-type accommodating space, where shapes of cross sections of the two sections are trapezoidal and semicircular.
- space for accommodating the quick female connector 50 and the slidable sleeve 51 can be formed, that is, the accommodating portion. It may be understood that a size of a cross section of the quick female connector 50 corresponding to the accommodating portion is greater than the size of the cross section of the slidable sleeve 51 .
- the two sides of the accommodating space may also be provided with holes of other shapes, which are not limited to the semicircular holes in this embodiment.
- both the lower mounting bracket 70 a and the upper mounting bracket 70 b are only internally provided with accommodating space (not shown) for disposing the quick female connector 50 and semicircular holes (not shown) that are provided on the two sides of the accommodating space and lead to the accommodating space, and the shape and the structure of the accommodating space correspond to the shape and the structure of the quick female connector 50 . That is, the shape and the structure of the accommodating space match the shape of the quick female connector 50 .
- the cross section of the quick female connector 50 is hexagonal.
- internal space of either of the lower mounting bracket 70 a and the upper mounting bracket 70 b is provided with accommodating space, the shape of the cross section of which is trapezoidal. Therefore, after the accommodating space of the lower mounting bracket 70 a and the accommodating space of the upper mounting bracket 70 b are butted, an accommodating portion for accommodating the quick female connector 50 can be formed.
- the diameter of the semicircular hole is less than a size of a cross section of the quick female connector.
- the mounting bracket 70 further includes a spring plate 73 and a button ejector pin 75 .
- the spring plate 73 is of an arch-shaped structure, and has a middle portion and two bending portions connected to two edges of the middle portion, the middle portion is provided with a long-strip-shaped hole, and one of the bending portions is provided with an arc-shaped hole that cooperates with the quick male connector 60 and is connected to the long-strip-shaped hole. Therefore, the spring plate 73 forms a hollow-out structure, and when the quick male connector 60 is inserted into the quick female connector 50 , the insertion is not interfered with by the spring plate 73 .
- the bending portion provided with the arc-shaped hole abuts the groove portion 53 of the slidable sleeve 51 , and the other bending portion is secured to the lower mounting bracket 70 a .
- the button ejector pin 75 has a bending section and an ejector pin section, the bending section is disposed at the bending portion, which is provided with the arc-shaped hole, in the spring plate 73 , and the ejector pin section is far away from the spring plate 73 .
- the ejector pin section of the button ejector pin 75 is pressed to the left first, the spring plate 73 is forced to deform using the bending section of the button ejector pin 75 and the slidable sleeve 51 is pushed to move to the left by a distance, and then the quick male connector 60 can be smoothly pulled out.
- the button ejector pin 75 is secured to a second end of the spring plate 73 .
- Water of the cabinet liquid cooling system 100 flows out of the LCS control unit 20 , and enters the liquid inlet unit 10 a by passing through the liquid inlet 11 of the flow allocation unit 10 ; then, flows into the quick female connector 50 and the quick male connector 60 by passing through the liquid delivery pipe 31 of the liquid supply branch 30 ; and then, enters the interior of the device handle bar 230 by passing through the liquid inlet pipe of the node pipe 40 ; after flowing by a circle in the device handle bar 230 , the cooling water flows out of the liquid outlet pipe of the node pipe 40 , flows to the liquid return pipe 33 by passing through the quick male connector 60 and the quick female connector 50 , and enters the liquid outlet unit 10 b of the flow allocation unit 10 ; and eventually, flows back to the LCS control unit 20 by passing through the liquid outlet 13 .

- The present disclosure relates to the field of cabinet heat dissipation technologies, and in particular, to a cabinet liquid cooling system and a cabinet.
- As use requirements become increasingly strict, heat dissipation of a chip with high power consumption, and energy conservation and emission reduction gradually become a principal contradiction faced by next generation information and communications technology (ICT) convergence. Liquid cooling, as an efficient heat dissipation solution, has been widely applied to fields, such as the defense industry, medical treatment, and mainframe computers. That a liquid cooling technology is introduced into a data center and directly acts on a heat source in a primary device is currently an efficient and feasible heat dissipation solution, and has a broad application prospect.
- In a typical liquid cooling system loop of an existing data center, a device cooling system is configured to transfer heat from a central processing unit (CPU), a memory, a power supply, and the like to a heat exchanger, and implement heat exchange with an upper-level cooling system. Even though the device cooling system is closely coupled to a rack and a primary device, pipeline layout occupies internal space of the rack, bringing many difficulties to rack design, device cabling, and installation and maintenance.
- In addition, the current data center generally uses an International Electrotechnical Commission (IEC) 600 wide standard rack, and a conventional pipeline layout solution of a device cooling system includes the following two solutions. First, a flow allocation unit is securely installed on the right side of a cabinet, and is located in front of a mounting bar, a quick connector is fixed on a node panel, a hose is connected to the quick connector and the flow allocation unit, and cabling is performed on the left side of the cabinet. Second, a flow allocation unit is securely installed on two internal sides of a column of a front door of a cabinet, a quick connector is installed on the flow allocation unit, and some cabling space is occupied. Advantages of the foregoing two solutions are a small change of a rack structure and good rack universality. However, there are also obvious limitations.

device handle bar 230 can form a circulation cooling pipeline together with the flow allocation unit 10 using theliquid delivery pipe 31, one of the quickfemale connectors 50, one of the quickmale connectors 60 and the liquid inlet pipe; and the liquid outlet pipe, one of the quickmale connectors 60, one of the quickfemale connectors 50, and theliquid return pipe 33, so as to perform cooling and heat dissipation on the electronic device disposed in thedevice handle bar 230. - In this embodiment, the liquid inlet pipe and the liquid outlet pipe are both connected to connector threads (not shown) on a panel of the corresponding
device handle bar 230 using threaded connectors (not shown), thereby implementing connection between the liquid inlet pipe and the correspondingdevice handle bar 230 and connection between the liquid outlet pipe and the correspondingdevice handle bar 230. - Exemplarily, the liquid inlet pipe and the liquid outlet pipe are both hoses.
- In this embodiment, a closed pipeline circulation system inside the
device handle bar 230 is similar to a water tank, and is not limited to this embodiment. A different water path structure may also be designed according to an actual structure of thedevice handle bar 230. - The quick
female connector 50 and the quickmale connector 60 are mutually suspended and inserted for cooperation, and are fastened using aslidable sleeve 51, which are shown inFIG. 3 ; theslidable sleeve 51, the quickfemale connector 50, and the quickmale connector 60 are coaxial, and theslidable sleeve 51 is axially movable. In this embodiment, agroove portion 53 is disposed on an external surface of theslidable sleeve 51. - The multiple quick
female connectors 50 are clamped and secured using a mountingbracket 70, are locked using a screw or a bolt (not shown) and a tapped hole 71 provided on the mountingbracket 70, and are then all securely installed on an inner side of theside wall 210 of the cabinet using a screw or a bolt (not shown). In this embodiment, the mountingbracket 70 is formed by butting alower mounting bracket 70 a and anupper mounting bracket 70 b that have a same structure. That is, the multiple quickfemale connectors 50 are clamped and secured by butting thelower mounting bracket 70 a and the upper mountingbracket 70 b, are locked using the screw and the tapped hole 71, and are then all securely installed on the inner side of theside wall 210 of the cabinet using the screw. - In this embodiment, the structure of the mounting
bracket 70 includes the following two different implementation manners. - First, as shown in
FIG. 4 , both thelower mounting bracket 70 a and the upper mountingbracket 70 b are internally provided with accommodating space (not shown) for disposing the quickfemale connector 50 and theslidable sleeve 51 andsemicircular holes 72 a and 72 b that are provided on two sides of the accommodating space and lead to the accommodating space, and a shape and a structure of the accommodating space correspond to shapes and structures of the quickfemale connector 50 and theslidable sleeve 51. That is, the shape and the structure of the accommodating space match the shapes of the quickfemale connector 50 and theslidable sleeve 51. Further, a structure of thelower mounting bracket 70 a is the same as a structure of the upper mountingbracket 70 b, the interiors of thelower mounting bracket 70 a and the upper mountingbracket 70 b are hollow structures, and two ends are separately provided with thesemicircular holes 72 a and 72 b leading to the interiors. Thelower mounting bracket 70 a and the upper mountingbracket 70 b are mutually butted, to form an accommodating portion (not shown) for accommodating the quickfemale connector 50 and theslidable sleeve 51. In this embodiment, the diameters of thesemicircular holes 72 a and 72 b are less than a size of a cross section of either of the quickfemale connector 50 and theslidable sleeve 51, which therefore can prevent the quickfemale connector 50 and theslidable sleeve 51 that are accommodated in the accommodating portion from being detached from the accommodating portion from thesemicircular holes 72 a and 72 b. - When the quick
female connector 50 and the quickmale connector 60 are connected, the quickmale connector 60 is inserted into the quickfemale connector 50, and when a side wall corresponding to the semicircular hole 72 a withstands the quickfemale connector 50, the quickmale connector 60 can be smoothly inserted. When the quickfemale connector 50 and the quickmale connector 60 are detached, a drawing force is exerted on the quickmale connector 60, and the quickmale connector 60 and the quickfemale connector 50 that are connected move towards one side of thesemicircular hole 72 b by a distance. When theslidable sleeve 51 is in contact with the side wall of thesemicircular hole 72 b, a leftward reactive force (in a location direction inFIG. 3 ) of thelower mounting bracket 70 a and the upper mountingbracket 70 b is exerted on theslidable sleeve 51, and therefore, the quickmale connector 60 can be pulled out. - In this embodiment, the cross section of the quick
female connector 50 is hexagonal, the wholeslidable sleeve 51 is of a cylinder structure, and the size of the cross section of the quickfemale connector 50 is greater than a transversal size of theslidable sleeve 51. Correspondingly, internal space of either of thelower mounting bracket 70 a and the upper mountingbracket 70 b is provided with two-section-type accommodating space, where shapes of cross sections of the two sections are trapezoidal and semicircular. Therefore, after the two-section-type accommodating space of thelower mounting bracket 70 a and the two-section-type accommodating space of the upper mountingbracket 70 b are butted, space for accommodating the quickfemale connector 50 and theslidable sleeve 51 can be formed, that is, the accommodating portion. It may be understood that a size of a cross section of the quickfemale connector 50 corresponding to the accommodating portion is greater than the size of the cross section of theslidable sleeve 51. - It may be understood that the two sides of the accommodating space may also be provided with holes of other shapes, which are not limited to the semicircular holes in this embodiment.
- Second, as shown in
FIG. 5 andFIG. 6 , both thelower mounting bracket 70 a and the upper mountingbracket 70 b are only internally provided with accommodating space (not shown) for disposing the quickfemale connector 50 and semicircular holes (not shown) that are provided on the two sides of the accommodating space and lead to the accommodating space, and the shape and the structure of the accommodating space correspond to the shape and the structure of the quickfemale connector 50. That is, the shape and the structure of the accommodating space match the shape of the quickfemale connector 50. In this embodiment, the cross section of the quickfemale connector 50 is hexagonal. Correspondingly, internal space of either of thelower mounting bracket 70 a and the upper mountingbracket 70 b is provided with accommodating space, the shape of the cross section of which is trapezoidal. Therefore, after the accommodating space of thelower mounting bracket 70 a and the accommodating space of the upper mountingbracket 70 b are butted, an accommodating portion for accommodating the quickfemale connector 50 can be formed. - In this embodiment, the diameter of the semicircular hole is less than a size of a cross section of the quick female connector.
- The mounting
bracket 70 further includes aspring plate 73 and abutton ejector pin 75. Thespring plate 73 is of an arch-shaped structure, and has a middle portion and two bending portions connected to two edges of the middle portion, the middle portion is provided with a long-strip-shaped hole, and one of the bending portions is provided with an arc-shaped hole that cooperates with the quickmale connector 60 and is connected to the long-strip-shaped hole. Therefore, thespring plate 73 forms a hollow-out structure, and when the quickmale connector 60 is inserted into the quickfemale connector 50, the insertion is not interfered with by thespring plate 73. The bending portion provided with the arc-shaped hole abuts thegroove portion 53 of theslidable sleeve 51, and the other bending portion is secured to thelower mounting bracket 70 a. Thebutton ejector pin 75 has a bending section and an ejector pin section, the bending section is disposed at the bending portion, which is provided with the arc-shaped hole, in thespring plate 73, and the ejector pin section is far away from thespring plate 73. - When the quick
male connector 60 and the quickfemale connector 50 are detached, the ejector pin section of thebutton ejector pin 75 is pressed to the left first, thespring plate 73 is forced to deform using the bending section of thebutton ejector pin 75 and theslidable sleeve 51 is pushed to move to the left by a distance, and then the quickmale connector 60 can be smoothly pulled out. In this embodiment, thebutton ejector pin 75 is secured to a second end of thespring plate 73. - Water of the cabinet
liquid cooling system 100 flows out of theLCS control unit 20, and enters the liquid inlet unit 10 a by passing through theliquid inlet 11 of the flow allocation unit 10; then, flows into the quickfemale connector 50 and the quickmale connector 60 by passing through theliquid delivery pipe 31 of the liquid supply branch 30; and then, enters the interior of thedevice handle bar 230 by passing through the liquid inlet pipe of thenode pipe 40; after flowing by a circle in thedevice handle bar 230, the cooling water flows out of the liquid outlet pipe of thenode pipe 40, flows to theliquid return pipe 33 by passing through the quickmale connector 60 and the quickfemale connector 50, and enters theliquid outlet unit 10 b of the flow allocation unit 10; and eventually, flows back to theLCS control unit 20 by passing through theliquid outlet 13. Therefore, a closed cooling water circulation is formed. - According to the cabinet
liquid cooling system 100 of the present disclosure, the flow allocation unit 10 is installed in a cabinet 200, and is located in space between a side wall of the cabinet 200 and a mounting bar of the cabinet 200, which therefore determines a manner of disposing a liquid supply branch 30 and anode pipe 40, and further determines that a quickfemale connector 50 and a quickmale connector 60 can be suspended and butted for cooperation. That is, a function that space from an electronic device to a door of the cabinet 200 and cabling space are not occupied can be effectively implemented using the flow allocation unit 10 that is securely installed on a single side of the cabinet 200 and is located in the space between the side wall of the cabinet 200 and the mounting bar of the cabinet 200 to cooperate with multiple liquid supply branches 30,multiple node pipes 40, and multiple pairs of quickfemale connectors 50 and quickmale connectors 60 that cooperate with each other. - Moreover, the quick
female connector 50 and the quickmale connector 60 are suspended and butted for cooperation, which does not occupy the space between a front panel of a device and the door of the cabinet and the cabling space, can effectively ensure that the front-access-cabled electronic device has sufficient cabling space, can further avoid a risk of cabling cables and water pipes together, and is convenient to operate and maintain a quick connector. - In addition, the flow allocation unit 10 is installed between the side wall of the cabinet and the mounting bar of the cabinet, and is hidden well, thereby facilitating implementation of a function of smooth switching between an air cooling cabinet and a liquid cooling cabinet.
- In addition, cooperation and detachment of the quick
female connector 50 and the quickmale connector 60 can be quickly and conveniently implemented in the two different implementation manners of the mountingbracket 70, which is convenient to operate and maintain. - What is disclosed above is merely embodiments of the present disclosure, and is not intended to limit the protection scope of the present disclosure. Therefore, equivalent variations made in accordance with the claims of the present disclosure shall fall within the scope of the present disclosure.
